When starting my game with BattlEye enabled, my SpeedFan (or potentially other hardware-related) software stops working. Please fix it!
BattlEye is blocking certain software that is using kernel drivers which contain known security issues that can be exploited by cheats. We cannot support such software and therefore cannot provide a fix. Please ensure that you are using the latest version of such software or, if there is no newer version available, contact the developer/vendor of the software to notify them of the problem.
